To verify the psychometric properties of the Brazilian-Portuguese version of the Falls Behavioral (FaB-Brazil) Scale in Parkinson's disease (PD).
Participants ( = 96) were assessed by disease-specific, self-report and functional mobility measures. Internal consistency of the FaB-Brazil scale was evaluated using Cronbach's alpha and inter-rater and test-retest reliability using intraclass correlation coefficients (ICC). The standard error of measurement (SEM), minimal detectable change (MDC), ceiling and floor effects, and convergent and discriminative validity were evaluated.
Internal consistency was moderate (α = 0.77). Excellent inter-rater (ICC = 0.90; < 0.001) and test-retest (ICC = 0.91; < 0.001) reliability were found. The SEM was 0.20 and MDC was 0.38. Ceiling and floor effects were not found. Convergent validity was established by the positive correlations between the FaB-Brazil scale and age, modified Hoehn and Yahr, PD duration, Movement Disorders Society-Unified Parkinson's Disease Rating Scale, Motor Aspects of Experiences of Daily Living, Timed Up & Go and 8-item Parkinson's Disease Questionnaire, and negative correlations between the FaB-Brazil scale and community mobility, Schwab & England, and Activities-specific Balance Confidence scale. Females showed greater protective behaviors than males; recurrent fallers showed greater protective behaviors than non-recurrent fallers ( < 0.05).
The FaB-Brazil scale is reliable and valid for assessing people with PD.
验证巴西-葡萄牙语版跌倒行为量表（FaB-Brazil）在帕金森病（PD）中的心理测量学特性。
通过疾病特异性、自我报告和功能移动性测量来评估参与者。使用 Cronbach's alpha 评估 FaB-Brazil 量表的内部一致性，使用组内相关系数（ICC）评估内部一致性和重测信度。评估测量标准误差（SEM）、最小可检测变化（MDC）、天花板和地板效应以及收敛和判别效度。
内部一致性中等（α=0.77）。发现了极好的重测者间（ICC=0.90； <0.001）和测试-再测试（ICC=0.91； <0.001）信度。SEM 为 0.20，MDC 为 0.38。未发现天花板和地板效应。FaB-Brazil 量表与年龄、改良 Hoehn 和 Yahr、PD 持续时间、运动障碍协会统一帕金森病评定量表、运动方面的日常生活体验、计时起立行走和 8 项帕金森病问卷呈正相关，与社区移动性、Schwab & England 和活动特异性平衡信心量表呈负相关，表明了该量表的收敛效度。女性比男性表现出更多的保护行为；复发性跌倒者比非复发性跌倒者表现出更多的保护行为（ <0.05）。
FaB-Brazil 量表可靠且有效，可用于评估 PD 患者。
